Acids & Bases

Front

What is an acid?

Back

An acid is a substance that donates protons (H+) in a solution and has a pH less than 7. Example: Orange juice.

Front

What is a base?

Back

A base is a substance that accepts protons (H+) and has a pH greater than 7. Example: Baking soda.

Front

What is the pH scale?

Back

The pH scale measures the acidity or basicity of a solution, ranging from 0 (very acidic) to 14 (very basic), with 7 being neutral.

Front

What is a neutral substance?

Back

A neutral substance has a pH of 7, meaning it is neither acidic nor basic. Example: Pure water.

Front

Front

What are some common uses of bases?

Back

Bases are used in cleaning products, soaps, and as antacids. Example: Sodium bicarbonate is used in baking.

Front

What is the relationship between acids and pH?

Back

As the concentration of hydrogen ions (H+) increases, the pH decreases, indicating a stronger acid.

What is the relationship between bases and pH?

Back

As the concentration of hydroxide ions (OH-) increases, the pH increases, indicating a stronger base.
